Get the data that is being loaded by jquery in PHP CodeIgniter

Question

I have this dropdown menu using form_helper in CodeIgniter:

  <?php if($materialType): ?>

    <?php 
    $material_options = array();
    foreach($materialType as $rows){
        $material_options[$rows->id] = $rows->category; 
    }                                       
    echo form_dropdown('materialType',$material_options,'','id="materialType"');
    ?>

<?php endif; ?>

  <div id="materials"></div>

The code above is inside a <form> tag and I have this script:

  <script type="text/javascript">
    var base_url = "<?php echo base_url(); ?>"; 
  </script>

  <script> 
    $(document).ready(function(){
        $(document).on('change','#materialType',function(){
                loadthis();                 
            });

            function loadthis(){
                var ID  = $('#materialType').val();

                var dataString = 'id='+ ID ;
            $.ajax({
                type: "POST",
                url: base_url + "index.php/admin/get_material",
                data: dataString,
                cache: false,
                success: function(data)
                    {
                    $('#materials').html(data);
                    }
                });     
            }

            loadthis();
        });

 </script>

And here is the code that is being loaded:

   <div id="materials">
   <?php if($materials): ?>
        <table>

            <th>Name</th>
            <th>Description</th>
            <?php foreach($materials as $row): ?>
            <tr>
                <td><?php echo $row->mname; ?></td>
                <td><?php echo $row->mdesc; ?></td>

                <td>
                    <button class="try" value="<?php echo $row->id; ?>">Add</button>
                </td>

            </tr>

    <?php endforeach; ?>

    </table>

<?php else: ?>
    <div class="alert alert-error" style="width:300px;">No Resource Available!</div>
<?php endif; ?>

   $(document).on('click','.try',function(){
            alert($(this).val());
            return false;
        });

And what i want is if the Add button is being click I can get the ID,mname and store it until the form is submitted.
How can I do that using .data() in jquery? or Any ideas on how to store it until the form is being submit.

I didn't thoroughly look at your code, but I noticed when you print your table rows in a loop you have the id="try" assigned to all of the rows. the html id-attribute is a unique identifier so the JS that is alerting the value will only return the value of the first id it will find (at least that's what i think). Try to use a class instread of an id and then use this in your js.

$(document).on('click','.try',function(){
    alert($(this).val());
    return false;
});
